I'll manage to trim down the software a little bit later so that we can just focus on the issue or the thing I did something wrong on.
Before I do that, imagine you use the Finger Paint example in ApiDemos. Before your canvas draw the path, you draw a background Bitmap "bgBitmap" first. Assume your canvas draws everything (bitmaps, paths,...) into a global Bitmap object "mBitmap". When I do a getPixels() on mBitmap into an array and sharpen the image, I simply see the curve in back but background bitmap seems OK. Maybe there is something I need to do with the canvas to merge path with the background bitmap? Thanks. On Dec 5, 7:30 am, Mike Reed <[email protected]> wrote: > The color seems fine.
